fan-control: presence-aware IPMI fan curve for the R730 PVE host

Browse source 
The iDRAC stock curve runs the CPU at ~72°C on the 7080 RPM floor even
under load (optimises for quiet, not cool). Add a bash daemon + systemd
unit that drives the chassis fans from CPU temp on two curves, picked by
garage occupancy (the server is in the garage): COOL when empty
(measured ~58-65°C under load), QUIET near the silent floor when the
ha-sofia garage door shows someone is there (open, or <15min since last
activity).

Manual fan mode is backstopped: bash EXIT trap + systemd ExecStopPost
hand fans back to Dell auto on stop/crash; CPU>=83°C or repeated IPMI
failures do the same. Pushgateway metrics (job=fan_control). 36 unit
tests cover the pure curve/hysteresis/presence/parse logic; DRY_RUN +
RUN_ONCE for integration checks. Deployed and verified on 192.168.1.127
(CPU 70->58°C in cool mode, hysteresis stepping confirmed).
